HBr + LiOH --> LiBr + H2O A neutralization reaction occurs in between an acid and also a base, and the products are normally a salt and water.
You are watching: Which skeleton equation represents a neutralization reaction?
The maximum amount of magnesium oxide produced during the reaction have the right to be, 3.9 grams.
Explanation : Given,
Mass of = 2.4 g
Mass that = 8.0 g
Molar massive of = 24.3 g/mol
Molar mass of = 31.9 g/mol
First we have to calculate the moles of and .
Now we have to calculate the limiting and also excess reagent.
The well balanced chemical equation is:
From the well balanced reaction we conclude that
As, 2 mole the react through 1 mole the
So, 0.099 moles of react v
From this us conclude that, is an excess reagent since the given moles are greater than the required moles and is a limiting reagent and it borders the development of product.
Now we need to calculate the moles of
From the reaction, us conclude that
As, 2 mole the react to offer 2 mole that
So, 0.099 mole that react to give 0.099 mole that
Now we have to calculate the massive of
Molar fixed of = 40.3 g/mole
Therefore, the maximum quantity of magnesium oxide produced during the reaction deserve to be, 3.9 grams.
Answer from: dookiefadep5n1tt
Explanation:From the well balanced reaction:
Mg + 1/2O₂ → MgO,
1.0 mole that Mg reacts through 0.5 mole that oxygen to create 1.0 mole that MgO.We should calculate the no. Of moles of (1.8 g) of Mg and also (6.0 g) the oxygen:
no. Of moles of Mg = mass/molar massive = (1.8 g)/(24.3 g/mol) = 0.074 mol.
no. Of mole of O₂ = mass/molar fixed = (6.0 g)/(16.0 g/mol) = 0.375 mol.
So. 0.074 mol the Mg reacts completely with (0.074/2 = 0.037 mol) of O₂ which be in excess.
Using cross multiplication:
1.0 mole the Mg create → 1.0 mol that MgO.
∴ 0.074 mol the Mg produce → 0.074 mol of MgO.
∴ The quantity of MgO produced = no. Of moles x molar fixed = (0.074 mol)(40.3 g/mol) = 2.98 g.
